Active Directory Replication

Active Directory
™
, the directory service that is included with Microsoft® Windows® 2000, is a distributed directory service. Objects in the directory are distributed across the domain controllers in a forest, and all domain controllers in a domain can be updated directly. Replication is the process by which the changes that are made on one domain controller are synchronized with all other domain controllers in the domain or forest that store copies of the same information. Data integrity is maintained by tracking changes on each domain controller and updating other domain controllers in a systematic way. Active Directory replication uses a connection topology that is created automatically, which makes optimal use of beneficial network connections and frees the administrators from having to make such decisions.
